Abstract
An artificial heart assembly is provided with a blood inlet conduit, a blood outlet conduit, a pump that pumps blood from the blood inlet conduit to the blood outlet conduit, and an internal electromagnetic coupler adapted to be implanted beneath the skin of a subject. A voltage regulator is operatively coupled to the internal electromagnetic coupler to generate an output voltage that is supplied to the pump. The voltage regulator causes the magnitude of the output voltage to be modulated in accordance with a transmit data signal. An external electromagnetic coupler is operatively coupled to generate an electric signal at least in part from the output voltage, and a decoding circuit is coupled to sense a parameter of the electric signal generated by the external electromagnetic coupler. The decoding circuit generates a receive data signal from the sensed electric signal, the receive data signal corresponding to the transmit data signal.
